Still no sound, and it still freezes when pausing and everything else it did before.
I'm not that surprised, typically a corrupted software install can't fixed via update. It was worth a shot.
So I see a few scenarios here, one is to get a means of writing to a microSD card and simply flash a new image onto the card you have. This assumes there is nothing wrong with the card (we've had at least one instance here with a bad SD card being the culprit). It's easy but you need a way to write to microSD, your Mac likely has a full-sized SD slot so an adapter would be necessary or a USB card reader/writer would also work.
Another possibility would be to buy a new fresh microSD card, they aren't expensive, and if you have a local outlet for those that might be easiest, though Amazon Prime is just 2 days of wait. I can steer you on which card to buy.
Yet another would be to contact Allo and ask them to send you a new card, I think they would/should do it, but I don't know that for sure and it could take a while if they send it from India (speaking of which did you buy the D1S from their European outlet, or from India)?
Lastly, you could arrange a refund with Allo as there is of course the possibility the actual D1S hardware is defective, and no software will work on that. I think that unlikely but certainly not impossible.
My advice would be to purchase not one but two microSD cards, assuming another $20 doesn't rub you too wrong. That way you can flash both a new Moode install onto one of them, but also Volumio onto the other. You'd then be able to easily compare the two just by swapping the microSD card out of the RPi3.
My 2 cents, er... actually I think I'm in for at least a buck fifty at this point
